Web14 More Graphs: Euler Tours and Hamilton Cycles 14.1 Degrees The degree of a vertex is the number of edges coming out of it. The following is sometimes called the \First Theorem of Graph Theory": Lemma 14.1 Suppose the graph has n vertices and a edges. Suppose the degrees of the graph are d 1;:::;d n. Then Xn i=1 d i = 2a: Proof. WebThis can be done. In graph theory terms, we are asking whether there is a path which visits every vertex exactly once. Such a path is called a Hamilton path (or Hamiltonian path). We …
